Origin uncertain: an Irish centre seems likely, considering the presence of Irish minuscule in the same palimpsest (see C.L.A., 7.1001). Used for rewriting in the late eleventh century, apparently in the monastery of Allerheiligen at Schaffhausen. The ex-libris 'Bibliothecae eccles. Scaphus. ad D. Johannem' (saec. XVI) is seen on the unnumbered fly-leaf.
